It lays but one great egg, spotted with purplish. [Thisspecies, which is larger than a Goose, is the only northern sea-fowl utterly deprived of the function of flight, andhas accordingly its wings reduced to exactly that size which is most efficient of all for subaquatic progression :they are not larger than very moderate-sized fins, and the limb-bones arc considerably weightier and less solidthan those of its congener; but we are not aware that tlie skeleton makes any approach in form to that of the PALMIPEDES. 255. Fig. 126.—Sternum of Penguin. Penaruins of the southern hemisphere, vvhicli are very distinct from the Auks. As a particularly rare visitant, thisspecies is allowed a place in the British Fauna.] The genus of The Penguins {Aptenodytes, Forster)—Is even less capable of flying than that of the Auks. Their little wings, covered with mere vestiges offeathers, which at the first glance resemble scales; their feet, placed farther back than in any other bird [the Grebes and Loons alone excepted,]only support them by bearing on the tarsus,which is widened like the sole of the foot of aquadruped, and in which are found three bonessoldered together at their extremities. Theyhave a small hind toe, directed inwards, andtheir three anterior toes are joined by an entiremembrane. These birds are found only in theantarctic seas, never going on shore except tobre
